The truth lies in neither. The biggest economic problems stem from rigidity. Money has such an extreme degree of rigidity, it is capable of traveling through both space and time unhindered. It's a time machine and massless particle all in one.
The reason why Austrian economics appeals to some people is either because they have an anti government axe to grind and want more trivial reasons to blame the government, they want to be on the receiving end of a regressive money system (gold bugs), macroeconomics are often abandoned in favor of microeconomics which hides the fact that local decision making can still result in seemingly coordinated failure and finally because they have mistaken moral beliefs about an amoral system most notably the myth of the protestant work ethic and the belief that the promise of work is their own personal property and it should be their right to delay redeeming that promise for all eternity.
I will repeat it again. There are no morals in economics. Anyone who worships savings and frugality in monetary terms is worshipping poverty in real terms. Eat your economic cake, it will be bigger tomorrow because of that and when somebody needs you to show restraint and want to borrow your slice, they'll tell you.
